The differences are that mechanical weathering breaks rocks into little pieces.. Chemical weathering not only breaks the rock but dissolves it.

1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
The rate of weathering also depends on the surface area that is exposed. Mechanical weathering breaks rocks into smaller pieces. As the pieces get smaller, their surface area increases. When this happens, there is more total surface area available for chemical weathering. The result is that weathering has more of an effort on smaller particles.
Weathering is the breaking down of particles, but did you mean erosion?
Weathering is the decomposition of earth rocks, soils and their minerals through direct contact with the planet's atmosphere. Metamorphism is the solid-state recrystallisation of pre-existing rocks due to changes in heat, pressure, and/or introduction of fluids. SImply put, weathering is the break down of rock (wear and tear) and Metamorphism is rock changing due to Heat,Pressure, and Chemically active fluids

In chemical weathering, there is a chemical reaction that causes weathering. Mechanical weathering is caused by fire, abrasions of water along a surface, animals, or freezing and thawing.
suck a dick ;)
Chemical weathering is the breaking down of a rock on a minute level, like the solution of minerals. Mechanical weathering is the breaking down of a rock, sometimes causing a crack through an entire strata, resulting in mass movement; but mostly mechanical weathering is as a result of a factor which causes the rock to physically separate.
occures when the chemical comosition of the rock changes
chemical weathering change will most likely make a new substance
Chemical weathering is which makes new substances, whereas physical weathering is where rock is changed into smaller pieces of the same substance.
biological weathering is when plants grow inside of a rock and break it apart, mechanical weathering is when rocks are broken apart by a force
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
Mechanical weathering results from abrasion of a surface chipping away at the surface and removing small pieces. Chemical weather results from chemical reactions occurring between the material of the surface and the surrounding environment. In both cases small amounts of material may be removed gradually through the weathering process. Because a surface may not be homogeneous, some parts will be more resistant to mechanical weathering than others, resulting in pitting where the material is weaker. Likewise, a heterogeneous surface will exhibit pitting from chemical weathering as the environment preferentially attacks the portions of the surface that are richer in the more reactive materials - again resulting in pitting.
